Hinge that takes to pieces

ABSTRACT

A hinge that takes to pieces for doors, cupboards, etc., comprising a male and a female part which slide around an axis. This hinge comprises two retractable pivots, each of which can be inserted into a corresponding housing in the female part. The female part comprises a cavity whose two extremities terminate in two portions of a sphere into which are lodged the stops comprising a housing for the retractable, interdependent pivots in the male part. The pivots are separated axially by a compression spring which holds them in position in the housing provided by the two stops.

The purpose of the invention is to create a hinge which is simple to produce and easy to assemble.

The purpose of this invention is to produce a hinge which can be used alone for a door or similar object of any dimensions whatsoever in such away as to facilitate and simplify erection.

The purpose of this invention is also to create an inexpensive hinge which takes up little space.

The purpose of this invention is also to produce a hinge with interchangeable stops of a hard, self-lubricating material without it being necessary to produce the entire female part of the hinge in this material. I

A hinge conforming to the invention is shown as a non-limiting example in the attached drawings, in which:

FIG. 2 represents a cross-section in accordance with lI-II of FIG. 1.

FIG. 3 represents a right-hand view of the male part of FIG. 1.

FIG. 4 represents a front-view section of a stop in accordance with the invention.

FIG. 5 represents a left-hand view of the stop in accordance with FIG. 3.

FIG. 6 represents a front-view of a cross-piece in accordance with the invention. 7

- FIG. 7 represents a side view of the cross-piece in according with FIG. 5.

FIG. 8 represents a front view of a pivot.

A hinge in accordance with theinvention, represented in FIGS. 1 and 2, comprises a female part 1 and a male part 2 capable of pivoting in relation to each other.

Generally, identical and symmetrical elements bear a simple reference number when described individually and the same reference number ending with a letter when such elements are incorporated in an assembly. I

The female part 1 comprises a framework 3 which is fixed either on the door frame, or on the door itself, or again may form part of the door or door frame. This framework 3 comprises a cavity 4 stamped, for instance, and perceptibly cylindrical in shape, with its two ends 4a and 4b forming portions of a sphere. This cavity 4 comprises two rear walls 4 and 4" (see FIG. 2), perceptibly flat, making a certain angle and connected by a flat bar. In this way, the particular shape of the cavity 4, and especially of the spherical ends 4a and 4b, allows the housing of two identical stops 5a and 5b in this method of realization. These two stops are held in position by a crosspiece 6 cut out of mild-steel sheet (see FIG. 6) whose ends 60 and 6b have been bent back at right angles. The two ends 6a and 6b of this cross-piece 6 bear perforations 7a and 7b which are of perceptibly the same diameter as the housings 8a and 8b in stops 5a and 5b.

The male part 2 is made up of a perceptibly cylindrical section 9 terminating in a lug 10 or similar device fixed, for instance, to the leaf of the door. The cylindrical section 9 comprises an axial perforation 11 of perceptibly the same diameter as housings 8a and 8b. This cylindrical section 9 comprises, in addition, a groove 12 (FIG. 3) which allows access to the perforation l l, as described below.

This perforation 11 comprises two pivots 13a and 13b separated by a spring 14. FIG. 8 shows in detail such a pivot 13 made up of a main part, preferably cylindrical, fitted with a peripheral groove 15.

The stop, represented in FIGS. 4 and 5, is made up of a spherical section truncated so that it adapts to the shape of ends 4a and 4b of the cavity 4. Moreover, the housing 8 of this stop bears on its frontal edge a groove 16 of appreciably larger diameter than housing 8 proper. This groove 16 is intended to receive the rim 17 (see FIG. 6) of the cross-piece 6.

The cross-piece 6 (FIGS. 6 and 7) is made up of a steel element whose ends 6a and 6b are identical in shape to the smooth face of stops 8a and 8b, when the portion connecting these two ends 6a and 6b adapts itself in the bottom 4" of the cavity 4.

Such a hinge is assembled in the following manner:

The framework 3 is made fast first of all, preferably on the fixed section, afler which the fastening 10 is made fast on the movable section of the assembly. Then the two pivots 13a and 13b are brought closer together externally by hand so that they are concealed in the cylindrical section 9. This cylindrical section 9 can be inserted between the two ends 6a and 6b of the cross-piece 6. As a matter of fact, the stops 8a and 8b are placed, in a preliminary assembly, in the cavity 4 and held separated by the aforementioned cross-piece. As this crosspiece is elastic, it is possible to produce this assembly with stops 8a and 8b and a cross-piece 6 having a minimum amount of clearance between them. This assembly is locked in position by the ratchet mechanism of the rims 17a and 17b of the cross-piece 6 in the groove 16 of the stops 8a and 8b.

In this way, a simple false maneuver or a shock when the cylindrical section 9 is inserted between the ends of the crosspiece 6 is insuflicient to disturb this assembly.

When the cylindrical section 9 is well positioned in the housing so prepared, the two pivots 13a and 13b enter into the housings 8a and 8b and are held thereby by the action of the spring 14. Such a hinge is as easy to take to pieces as it is to assemble. It is sufficient to retract the pivots 8a and 8b by acting on the grooves 15 of the said pivots, using pliers or hooks. The male part can then be withdrawn from its housing.

To prevent the pivots 8a and 8b from slipping right out of the perforation 11, it is alsopossible to hold them there by means of a fork-shaped element which is gripped in the grooves 15a and 15b and one end of which rests at the end of its course against the corresponding end of the groove 12.

The easy assembly and taking to pieces, as well as the method of production, of this hinge composed of independent elements permit the interchangeability of the divers worn elements. Moreover, it follows from the foregoing that it is possible to produce, for example, the framework 3 in a stamped mild-steel, or a relatively fragile light material, while the stops can be produced in a special, treated steel. The saving of time and material is thus appreciable.

The same goes for the male part 2 whose pivots 13a and 13b can be produced in a more expensive metal than the rest of the part 2.

Of course, the invention is'not restricted to the production example described and represented above; from this example it is possible to foresee other production variants which in no way exceed the limits of the invention.
